Title: Test for brake fluid age and condition
Inventor: PETTY JON A
IPC: G01N21/78
Filed: 2000-07-20
Granted: 2004-11-16
Abstract: A reactive test strip (10) having a pre-exposure color is used to measure and indicate the concentration of copper ions in brake fluid in terms of a readily visible color change. The strip is immersed in the fluid within a brake fluid container (30) and any resulting color change is compared to a color chart (20) and a known test standard representative of the maximum concentration determined empirically to correspond to a boiling point considered safe for normal operation. If the color change indicates a higher copper concentration, then the fluid is considered inadequate for safe operation and thus recommended for replacement without further tests. Similar copper or metal strips can also be used to determine iron or zinc concentration. An automated embodiment of the invention includes an optical instrument to compare the color obtained during the test against a predetermined test standard and determine whether a brake fluid change is recommended.

Abstract: On décrit un procédé d'estimation depuis la surface des propriétés d'un réservoir dans lequel la position du réservoir et les résistivités terrestres moyennes au-dessus, au-dessous et à proximité dans le sens horizontal du réservoir (3) sont d'abord déterminées au moyen des données géologiques et géophysiques au voisinage du réservoir (3). Ensuite les dimensions et la fréquence de test pour une source électromagnétique (4,5) sont déterminées afin de maximiser sensiblement les courants électriques verticaux et horizontaux transmis au niveau du réservoir (3). La source électromagnétique (4,5) est ensuite activée au-dessus du réservoir (3), de manière approximativement centrée et une pluralité d'éléments de réponse électromagnétique est mesurée avec un réseau (10) de récepteurs. Des contraintes de paramètres géométriques et électriques sont déterminées, au moyen des données géologiques et géophysiques. Puis la réponse électromagnétique est traitée et dans ce traitement les contraintes de paramètres géométriques et électriques sont utilisées pour produire des images de profondeur de la résistivité verticale et horizontale inversées.

Title: Dynamic jitter buffering for voice-over-ip and other packet-based communication systems
Inventor: MORAN CHRISTOPHER
IPC: H04L12/56
Filed: 2002-07-15
Granted: 2006-11-07
Abstract: A variable-size jitter buffer is used to store information associated with a voice signal, facsimile signal or other received signal in a receiver of a packet- based communication system. The receiver determines an appropriate adjustment time for making an adjustment to the size of the buffer based at least in part on a result of a signal detection operation performed on the received signal. For example, in the case of a received voice signal, the determined adjustment time may be a time at which a state machine associated with a speech detector is in a "no speech" state. If the actual buffer size at the determined adjustment time is not within a designated range of a target computed at least in part based on one or more jitter measurements, the buffer size is adjusted at the determined adjustment time, e.g., by an amount representative of the difference between the actual buffer size and the target. The invention provides low-delay and low-complexity jitter buffering particularly well suited for use in an Internet Protocol (IP) receiver of a voice-over-IP system.

Granted: 2008-12-30
Abstract: A vehicle door latch (10) has a housing (2) having a mouth (4) for receiving a striker. A ratchet (56) is pivotally mounted to the housing for rotation between latched and unlatched conditions.  The ratchet (56) cooperates with the mouth (4) to selectively retain a striker. A pawl (62) is mounted to the housing (2) for releasably engaging the ratchet (56). The pawl (62) is moveable relative to the ratchet (56) between a rest position engaging the ratchet to block movement of the ratchet toward the unlatched condition and a released position disengaging the ratchet to allow movement of the ratchet toward the unlatched condition.  A release lever (22) is mounted to the housing and operably connected to the pawl (62) by a clutch lever (94) extending therebetween.  The clutch lever (94) is moveable between an engaged position operably connecting the release lever (22) to the pawl (62) effecting movement of the pawl toward the released position and a disengaged position operably disconnecting the release lever from the pawl.  A locking lever (100) is mounted to the housing for moving the clutch lever (94) between the engaged and disengaged positions.  The clutch lever (94) moves in a first plane (19) to effect movement of the pawl and the locking lever moves the clutch lever out the first plane (19) to effect movement between the engaged and said disengaged positions.

Title: Permanent magnet excited electric machine and method of operating such a machine
Inventor: EHRHART PETER
IPC: H02H3/02
Filed: 2001-02-21
Granted: 2011-08-23
Abstract: If an interturn short-circuit occurs in a stator coil winding of a permanent magnet excited electric machine, a short-circuit current is produced there that results in an electrically induced magnetic alternating flux which corresponds in its value to the permanent magnetic alternating flux flowing through the respective winding and which is opposite in phase. Such a short-circuit current could lead to burn-off of the turn due to its considerable strength and the loss associated therewith. To prevent this, the invention suggests in case of detection of an interturn short-circuit, to entirely short-circuit at least the coil affected by the short-circuit or to apply thereto a corresponding in-phase current and to reduce the excessive short-circuit current in the individual turn or in the individual turn section by way of this overall short-circuit current in the coil. It is thus possible to prevent burn-off of the respective turn part.

Abstract: The invention concerns an optocoupler. The optocoupler includes a substrate made of optically opaque electrically insulating material metallized to provide conductive traces on a top surface thereof which are electrically linked to metal pads on a bottom surface. A cadmium sulfoselenide photoresistor having an active surface is placed over the substrate with the active surface facing the substrate where the photoresistor has two electrodes. Metal leads connect each of the two electrodes of the photoresistor to two metallized traces on the substrate. A light emitting diode (LED) chip is mounted on the substrate facing the active surface of the photoresistor. The LED chip has a top and bottom electrode, where the bottom electrode is electrically attached to a third metallized trace and the top electrode is wire bonded to a fourth metallized trace. A cover made of optically opaque material is fixed to the substrate so as to enclose the photoresistor and the LED chip in a light tight enclosure. In an alternative embodiment of the invention, the photoresistor and the LED chip can lie side by side and be in optical communication with each other through a reflective coating on the inside of the cover.
